Evening all
I recently bought my first boat, a 1990 Bavaria 300 fin keel and want to make a couple of alterations to the existing navigation equipment.
Is it possible that someone can guide me through a “Red goes here and Black goes there” type of guide to make my desired changes, without scaring me with the technical jargon ?
I APOLOGISE IN ADVANCE FOR THIS LONG-WINDED DESCRIPTION !
The nav equipment is mounted in a ‘home-made’ instrument panel mounted on the wheel steering column. It includes a Raytheon Autohelm Talking ST50 Multi and a speaker which badly affected the binnacle compass. Inside the panel the talking arrangement incorporated a small junction box and a larger plastic box (marked Autohelm). There appears to be a variety of relevant protective devices fitted in-line.
Because the ‘Speaking’ facility is not required I removed the speaker and end-of-line Autohelm box and would like to install a Garmin 551 Chartplotter in the redundant speaker position. I have temporarily surface mounted the chartplotter in this position and linked in a NASA AIS ENGINE which works well.
I hasten to add that the remaining equipment also appears to work well.
There is also a Garmin GPS 128 fitted at the chart table which I assume is linked into the nav equipment in the cockpit instrument panel. I have yet to learn how to use the equipment to its best advantage.
I have drawn a layout of the equipment with a few lines showing cable runs, definitely not a wiring diagram, and will attempt to attach it to this thread. Fingers crossed.
DESCRIPTION OF CABLE CONNECTIONS AND COLOUR CODINGS
A “Common Cable” enters the panel to a 3 way plug assembly then links (in series) to a RAYTHEON ST60 MULTI, then to a RAYTHEON ST60 SPEED, then to a RAYTHEON ST60 DEPTH then to a small junction box. It then continues to a RAYTHEON AUTOHELM TALKING ST50 MULTI.
From the TALKING ST50 there are 2 cables entering a grey/cream coloured box (appx 6” x 3” x 1”) labelled AUTOHELM. Leaving this box are 2 cables, one was connected to the speaker the other was left spare (It is this box and speaker I have removed).
There is a second “Common Cable” from the 3 way plug assembly to a RAYMARINE ST40 COMPASS.
Colour markings (on units) next to the “Common Cable” socket inlets / outlets = RED GREY YELLOW
On the back of the MULTI, SPEED and DEPTH is marked SEATALK
..............................................................................................................
Also entering the panel are the following individual cables:
One cable to the NMEA IN connections on the MULTI. The BLUE core to RED + and BROWN (or BLACK – can’t remember !) to the BLUE –
One cable to the SPEED with the cores connected to their matching colours – RED, GREEN, WHITE, BROWN with (I think) the ‘screen’ to the remaining connection
One cable to the COMPASS with RED, GREEN, YELLOW, BLUE and the ‘screen’ connected.
One cable to the DEPTH with WHITE (?), BLUE and BLACK (?) connected. Poor photo !
..............................................................................................................................
QUESTIONS: Is it possible to link from the NMEA OUT connections on the MULTI to the GARMIN CHARTPLOTTER ?. If so what cables should be used from the Garmin cable loom and what would the benefits be ?.
Is it also possible to link from the Garmin cable loom to other units (SPEED, DEPTH etc) and what would the benefits be?.
As previously mentioned, there is a link between a separate AIS Engine and the Garmin Chartplotter which works well (as a temporary installation)
...........................................................................................................................
Equipment information supplied with unit (which I am probably writing needlessly):
Nasa Marine A.I.S. Engine
The AIS Engine receives AIS data, converts it to an NMEA format, and sends it on to any display equipped to receive it. The engine can also receive NMEA information from any GPS receiver (at 4800 baud) which it then sends on to the display with the AIS data (at 38,400 baud).
Connect the power cable to the 12 volt supply. If a GPS is to be fitted then connect the GPS NMEA output (or NMEA+VE) to the blue fly lead of the data cable. If the GPS has a NMEA-VE (or NMEA REF) connect this to the supply negative. Ensure the GPS is connected to the same negative supply as the AIS Engine. The NMEA 0183 signal from the GPS must swing above and below 2 volts (ref to the supply negative) and contain the RMC. CHINESE TO ME !!!.
Garmin 551 Chartplotter
A list of the wiring harness cables and connections:
Wire Colour Wire Function
Red (Fused) Power (10 -32 Vdc)
Black Ground (power and NMEA 0183)
Blue NMEA 0183 port 1 Tx (out)
Brown NMEA 0183 port 1 Rx (in)-------Connected to AIS
Grey NMEA 0183 port 2 Tx (out)
Violet NMEA 0183 port 2 Rx (in)
Green CANet L (if applicable)
White CANet H (if applicable)
Orange Accessory on
Yellow Alarm low
PHEW ! SOMEBODY STOP ME !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This really is going on and on and I bet there are one or two of you (or more) having a bit of a chuckle, or more likely fallen asleep. I’m sure to those of you with the knowledge what I’m asking is just for a couple of straightforward connections and nothing more.
So back to my original question:
Can somebody please give me a simple Red goes here and Black goes there type of guide.
Please have patience with us “uninformed types” (more to the point – ME)
Many sincere thanks to those prepared to offer assistance
